Outcome Measures: Prior imaging studies note that tasks requiring attention modulation, emotional memory, social interchange, and fear conditioning engage brain regions previously implicated in adult mood and anxiety disorders. These regions include most consistently the amygdala and ventral prefrontal cortex. Moreover, imaging studies of reward function implicate the striatum and prefrontal cortex in adult mood disorders. As a result, we hypothesize that attention, memory, social interaction, reward, and conditioning paradigms will engage the amygdala, ventral prefrontal cortex and striatum in both psychiatrically healthy and impaired
